Replace Water Temperature Sensor on a York Chiller

Job Description:  Replace Water Temperature Sensor on a York Chiller

Area: London

Issue Identified:  Following a planned preventative maintenance attendance our engineer advised that the York Chiller required some remedial works to be carried out. Compressor 1 has a history of oil trips, oil and filter replacement was required. Leaving water temperature sensor required replacing. Pressure relief valves were out of date and required replacement.

Works carried out:

  • Isolated the York Chiller unit electrically and mechanically.
  • Recovered refrigerant from circuit A into a dedicated recovery cylinder.
  • Weighed and confirmed charge in the circuit.
  • Drained oil out of the system.
  • Removed and replaced oil filters.
  • Pressure tested with OFN (oxygen free nitrogen) to locate any possible leaks.
  • Once proved released OFN to atmosphere and evacuated system to a minimum of 2 Torr.
  • Re-charged with recovered refrigerant.
  • Replaced the PRV’s (pressure relief valve) on the second circuit.
  • Replaced leaving water sensor.
  • Reinstated power to the York Chiller.
  • Test ran and re-commissioned.
  • Completed waste transfer note and handed to on-site representative.
  • Completed F Gas records.
